Gross Misconduct in the Workplace: Managing Aggressive Employee Behaviour
Gross misconduct refers to serious breaches of workplace conduct that may justify immediate dismissal. For example, if an employee consistently behaves aggressively, becomes easily angered, or intimidates others—creating a hostile work environment—employers may take disciplinary action. According to Fair Work, such behavior can lead to a formal warning or termination based on general or gross misconduct.
Unfair Dismissal Claims and Gross Misconduct
Across Australia, many unfair dismissal claims have been filed in response to misconduct. In most cases, Fair Work has ruled in favour of the employer, especially when the behaviour involved bullying or harassment.
One recent case involved an employee dismissed for gross misconduct after displaying aggressive behaviour in meetings, intimidating colleagues, and making derogatory comments toward management.
Case Outcome
The case was adjourned for nearly a year due to the employee’s mental health concerns, which prevented participation in the investigation and “show cause” meetings. Nevertheless, Fair Work ruled the dismissal reasonable and awarded the employee five weeks’ pay in lieu of notice.
What Fair Work Considers in Misconduct Claims
When reviewing misconduct-related claims, Fair Work evaluates several factors:
- The impact of the behaviour on colleagues and workplace culture
- Whether the employee shows remorse or apologises
- The employee’s understanding of acceptable workplace behaviour
- Evidence that the misconduct will not happen again
